IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 160.683, dated March 9,1875; application tiled October 1, 1874.

To all whom it may concern:

Be it known that I, FREDERIC KAMPEE, of the city, county, and State ofNew York, have invented a certain new and useful Improvement in Lamps,of which the following is a speciiication This invention is illustratedin the accompanying drawing, in which- Figure l represents a verticalsection when the lamp is in position to receive a fresh supply of oil.Fig. 2 is a similar section ot the same when the lamp is upset. Fig. 3is a detached section ot' the valve in a larger scale than the previousfigures.

Similar letters indicate corresponding parts. This invention relates toimprovements in that class ot lamps which are provided with a valve anda weighted rod to prevent the valve being opened if the lamp shouldupset.

My invention consists in a peculiar con struction and combination ofparts, which will be 'ull y hereinafter described, and pointed out inthe claims, whereby the operation of the valve is much more perfect andreliable than as heretoi'ore constructed.

In the drawing, the letter A designates the cistern of a lamp, which ismade oi' glass, or any other suitable material, in the usual or anyconvenient form or shape. On the upper part of this cistern is formedthe neck D for the reception of the burner, and near this neck issituated a valve, B, which is composed of a flanged head or cap, a, fromwhich extend downward three, more or less, spring-arms, b, which are.held in position by rings c d. The upper ring c is made to tit atubular socket, O, which'is itted in an opening in the oil-cistern, andis provided with a flange, c1, the upper surface ot' which forms avalve-seat, c2, for the valve. The spring-arms b are provided withoutwardly-projecting inclined shoulders e, so that, when the valve israised to the position shown in Fig. 1, it Will retain its position inthe tlanged tubular socket C by friction, and the cistern Acan beconveniently illed with oil;

If desired, the valve can be entirely withdrawn, so as to have the tubeC wholly open for the reception `of the oil.

On the inside of the lower ring d is formed a shoulder, f, and in thetube C is secured a loop, g, which supports a pendulum, E, the upper endof which forms a hook, h. lit' the lamp is upset, as shown in Fig. 2,this hook catches over the shoulder fof the ring d, and the valve isprevented from leaving its seat. By these means the spilling of oil isprevented. At the same time the pendulum retains the valve with ayielding force, so that,it an explosion shouldtake place at the momentor after the lamp is upset, the valve will be blown out, and all dangerarising from the explosion will be avoided.

By these means the use of a safety-valve on the. cistern ot' a lamp isrendered practicable and free from all objections.

I disclaim everything shown and described in my Patent No. 143,452.

What I claim as new, and desire to secure by Letters Patent, is-

1. The valve B, having the shoulder fand spring arms b, constructed withinclined shoulders c, in combination with the pendre lum E, having atits upper end a hook, l1., for engaging With the shoulder f on the valveshould the lamp upset, substantially as and for the object specified.

2. The valve B, constructed with the dan ged head or cap a, rings c d,and the spring-arms b, having the inclined shoulders e, in combinationwith the tube C, having the valveseat c2, substantially as and for thepurpose described.

In testimony that 1 claim the foregoing I have hereto set my hand andseal this 28th day ot September, 1874:.
